Plumber guides and answers

Santa Ana Plumbing Co arranges a local plumber for homes across Santa Ana and nearby Orange County cities, and these guides are the plain answers we wish every homeowner had before the first phone call. They cover what common plumbing jobs cost, what moves the price, what you can safely check yourself and when the law says a contractor has to do the work. When you are ready, you can ask for a written quote, or read how a job works on the how it works page.

Prices on these pages are guides taken from published sources, not quotes. The written price comes after a visit.

Where should I start if something is leaking or has stopped working?

Start with the guide that matches what you can see: water where it should not be, no hot water, a toilet that will not stop running or a drain that will not clear. If water is escaping fast, shut off the main valve first, then read the burst pipe and leak guides below. For any gas smell, leave the building and call SoCalGas from outside. The area pages cover each city we serve and who handles permits there.

The guides by topic

Every guide on this site is listed below under the kind of job it covers, from water heaters and leaks to toilets, repiping, gas lines and permits. Each line says what the page answers, so you can pick the one that matches your problem and skip the rest.
